PLANNING 03 – ARCH. DAVID A. BAUTISTA instructor

EKISTICS (SCIENCE OF HUMAN SETTLEMENTS) - starts with the premise that human settlements are susceptible of systematic investigation". – Constantine A. Doxiadis

The Principles 1. The first principle is maximization of man's potential contacts with the elements of nature (such as water and trees), with other people, and with the works of man (such as buildings and roads). In this, man differs from animals; we do not know of any species of animals that try to increase their potential contacts with the environment once they have reached the optimum number of contacts. Man alone always seeks to increase his contacts. 2. The second principle is minimization of the effort required for the achievement of man's actual and potential contacts. He always gives his structures the shape, or selects the route, that requires the minimum effort, no matter whether he is dealing with the floor of a room, which he tends to make horizontal, or with the creation of a highway. 3. The third principle is optimization of man's protective space, which means the selection of such a distance from other persons, animals, or objects that he can keep his contacts with them (first principle) without any kind of sensory or psychological discomfort 4. The fourth principle is optimization of the quality of man's relationship with his environment, which consists of nature, society, shells (buildings and houses of all sorts), and networks (ranging from roads to telecommunications). This is the principle that leads to order, physiological and aesthetic, and that influences architecture and, in many respects, art. 5. Finally, and this is the fifth principle, man organizes his settlements in an attempt to --achieve an optimum synthesis of the other four principles, and this optimization is dependent on time and space, - on actual conditions, and on man's ability to create a synthesis. When he has achieved this by creating a system of floors, walls, roofs, doors, and windows which allows him to maximize his potential contacts (first principle) while minimizing the energy expended (second principle) and at the same time makes possible his separation from others (third principle) and the desirable relationship with his environment (fourth principle), we speak of "successful human settlements". What we mean is settlements that have achieved a balance between man and his man-made environment, by complying with all five principles. WHAT IS THE EXTENT OF HUMAN SETTLEMENT? -

The distance man wants to go or can go in the course of his daily life. The shortest of the two distances defines the extent of the real human settlement, through definition of a "daily urban system" The process starts with the circle whose radius is defined by man's willingness to walk daily up to a certain distance and to spend a certain period of time in doing so (the limit for the rural dweller is 1 hour, or 5 kilometers, for horizontal movement; the limit for the urban dweller is 20

minutes, or 1 kilometer). This leads to the conception of a circular city, and of a city growing in concentric circles If we turn back in history we find, however, that, throughout the long evolution of human settlements, people in all parts of the world tended to build an urban settlement which reached an optimum size of 50,000 people and physical dimensions such that everyone was within a 10-minute distance from the center. There is no question that, for people who depend on walking as a means of locomotion, this unit is the optimum one from the point of view of movement and social interaction through direct contacts between people. Also, experience has shown that, for people who can walk, it is a maximum one from the standpoint of aesthetics; for example, creation of the Place de la Concorde in Paris cut from the total 3500-meter length of the Champs Elysees a length of 2100 meters, a distance from which one can reach, and enjoy, the Arc de Triomphe on foot. It is also perhaps an optimum one from the social point of view; for example, Pericles in ancient Athens could get a reasonable sample of public opinion by meeting 100 to 150 people while walking from his home to the Assembly.

The Quality of Human Settlements Judgement about quality can be made in several ways in terms of the relation of every individual to his environment that is, his relation to nature, society, shells, and networks - and the benefit that he gets from these contacts. We can measure his relations to air and to its quality; to water in his home, in the river or lake, and at sea (its quality and his access to it); and to land resources (their beauty and accessibility) and the recreational and functional facilities provided by them;

WHAT IS MORPHOGENESIS Morphogenesis - is the development of body shape and organization. WHAT IS SYNTHESIS? The combining of separate elements or substances to form a coherent whole. The complex whole so formed. Morphogenesis -

Formation of the walls. Two separate non-connected rooms (left) can remain independent units, but people tend to bring them together. Two separate, connected rooms (middle) cannot remain independent units; they create many problem surfaces. Two connected rooms (right) tend to eliminate the problem surfaces; they tend to occupy a minimum total area Morphogenesis in human settlements varies with the type of unit we are dealing with. From the many types of units I will select the room (the No. 2 unit) and will follow its formation. We do not know how and when the formation of a room started. It probably started in many parts of the world, and probably the rooms had many forms and sizes. We have reason to believe that the first rooms were of moderate size (according to today's standards), but they may have been very small one-man/ one-night huts similar, in a way, to those built and used by the apes In any case the moment came when some primitive people had round huts and others had orthogonal ones, and when there were different types of roofs or, in some cases, no roofs at all. In at least one modern instance - that of the Bushmen of the Kalahari Desert in southwest Africa - there is no door to the hut; the Bushmen jump into it over a wall (Ref. 13).

Two myths If we can analyze the problem of quality and understand the morphogenetic process which should enable people to build properly and improve an undesirable situation, why are conditions so bad in our cities? MYTH NO.1 - Myth of the city of optimum size. Some define optimum size as being related to the income of the people; but in a developing world, Where the average per capita income increases by 2 percent a year (and by more in urban areas), what is the meaning of this optimum over a long period? Others argue in terms of optimum numbers of people and of organization and, more specifically, municipal efficiency, but they are not able to produce any convincing proof (Ref. 17). Even if they could, comparisons of one city with another have no meaning in a world where people no longer live in isolation. Others base optimum size on organizational aspects such as one school or one hospital for so many children or people. But, in a world of changing ratios between age groups and of changing technical and managerial abilities, this line of thinking cannot lead anywhere. Such considerations are very useful for calculating needs which have to be satisfied in certain areas and periods, but not for calculating the optimum size of the city. Technological calculations based on the means of transportation cannot be helpful either. 5 | Page


MYTH NO. 2 Another myth which still prevails is that we can solve the problems of our cities through the conception, and official recognition, of a physical plan expressed by a two- or three-dimensional drawing. But our cities are growing organisms. They need a development policy leading to a development program which is expressed, in space, by physical development plans, but they also need economic, social, political, administrative, technological, and aesthetic programs.

Human settlements are no longer satisfactory for their inhabitants… � economically speaking - don’t have the means to satisfy their basic needs - remain homeless or live in houses of very low quality � social point of view - man appears to be lost in the big cities - feels abandoned by progress in many small towns/villages � political level - new types of societies and new types of people have not found their corresponding political institution. � technical point of view - most settlements don’t have the facilities indispensable to their proper functioning in spite of the technological achievements � aesthetically - the ugliness of human settlements around Creating better conditions for tomorrow can be understood better if we look into the different elements of the human settlements…

Human Settlements & their Elements 6 | Page


Human settlements are settlements inhabited by man. Human settlements should satisfy man. Human settlements consist of: a. the CONTENT (man, alone or in societies) b. the CONTAINER (or the physical settlement, which consists both natural and man-made or artificial elements) When taken together make up the human settlement whose largest possible dimensions are defined by the geographic limits of the earth’s surface. The total surface of the Earth: � the largest possible container of man � the whole cosmos of man � the cosmos of the Anthropos � the anthropocosmos

Such definition of human settlement implies that it is not merely 3-dimensional but 4-dimensional. . . - man & society change continuously and by so doing, create functions which unlike shells (which can be conceived in 3-dimensional terms) require a fourth dimension ---TIME in order to be carried out - a 3-dimensional conception of a settlement is very like a film which suddenly stops and arrest all the figures in their movements. A still photograph of a building looks real only if there are no human figures in the pictures; if people have been arrested in the process of walking in front of the building, then the picture is frozen, unreal. A human settlement needs both categories of elements in order to come into existence… � man alone or in groups, if not settled anywhere cannot be said to form a settlement or even a part of one. � once he does settle somewhere even temporary, we have a temporary, elementary settlement in which a pattern of relationship between man and his container comes into existence for a certain period of time (one day, many

7 | Page


days, or one season) regardless of whether the container is a natural one ( a cave) or man-made (tent or a building). Nature alone, without man, cannot be said to form a settlement or even a container, since it has no human content… � a man-made settlement is only the corpse or the abandoned shell of a settlement, which must be considered dead as in any other corpse. � some people call dead settlement a “settlement” but this is no more correct calling the shell of a snail a snail. � term is used in many such cases for reasons of simplicity, but this is not accurate and should be used with care to avoid confusion.

2 basic elements of human settlements (Doxiadis) THE CONTENT AND THE CONTAINER This can be further subdivided into 5 categories (in hierarchical order) (Container) � NATURE – providing the foundation upon which the settlement is created and the frame within it can function (Content) � MAN – an individual, Homo sapiens - Biological needs (oxygen, nutrition) - Sensation and perception (5 senses) - Emotional needs (satisfaction, security, sense of belonging) - Moral values (Content) � SOCIETY – a group of individuals sharing the same culture, values, norms, and traditions (Container) � SHELLS or the structures within which man lives and carries out his different functions, the built component. 8 | Page


(Container) � NETWORKS or the natural and man-made system which facilitate the functioning of the settlement, or links within the settlement, roads, communications systems, utilities, etc. Hierarchy of human settlements… � a hamlet, a neighborhood, a small village � a community, a town � a city, an urban area � a metropolis � a conurbation – a composite of cities, metropolises, urban areas � a megalopolis – merging of two or more metropolises with a population of 10M or more; a 20th century phenomenon (Megalopolis - concept coined by Jean Gottmann for urban complexes in the Northeastern United States.) … A hierarchy of settlements is characterized by a few large cities, some mediumsized cities, and many small settlements.
